HCPL-2430-500E HCPL-2430-000E RF Integrated Circuits High Speed Optocouplers 20MBd 2Ch 4mA

Description

The HCPL-2400 and HCPL-2430 high speed opto-cou- plers combine an 820 nm AlGaAs light emitting diode with a high speed photodetector. This combina-tion re- sults in very high data rate capability and low input cur- rent. The totem pole output (HCPL-2430) or three state output (HCPL-2400) eliminates the need for a pull up re- sistor and allows for direct drive of data buses.

The detector has optical receiver input stage with built- in Schmitt trigger to provide logic compatible wave- forms, eliminating the need for additional waveshaping. The hysteresis provides di erential mode noise immuni- ty and minimizes the potential for output signal chatter.

The electrical and switching characteristics of the HCPL- 2400 and HCPL-2430 are guaranteed over the tempera- ture range of 0°C to 70°C.
